If you try to jump the truck and the same thing happens, I would look at the starter or its connections.

Basically, you will have to look at the battery connections and the starter connections. Sounds like the key switch is working.
I pulled the positive cable from the battery to the starter. I got a complete replacement from the junkyard with the plugins than a completely new wire. Fro the ground I got a new ground cable and all new terminals for the battery.

Will be putting it in the truck tonight and report back.

So here's the deal changed both positive (+) and negative (-) cables. Now the issue is kinda different with the key on the ECU seems like it doesn't have any power. The relay isn't clicking at all. But if I would jump the main relay with a jumper the fuel pump relay will be clicking all day long. Pump doesn't prime when I have both relays plugged in.

I'm getting battery voltage at the main relay from the battery.

Secondly, I'm not getting spark at all.

Check the fusible links first to make sure you didn't blow them out. They supply power to the injectors. Here is a writeup on them:

If those are good, either your battery is not as good as you say or the ignition switch is bad.

Test the battery first. It should have about 13 volts on it.

Bought a new battery and installed it same issue. (Got a good deal on two of them).

The main concern now is that not getting any power at the computer with the key on with all the relays plugged in. Jump the main relay with a wire and now we got power and a clicking fuel relay.

Really have no idea what to check changed all the grounds I can see in the engine bay already. New main relays and fuel relays. New battery. New coils (both of them).

Now what else to check. This truck is making me frustared.

Checked them and saw that the previous owner hack them and just added a section of wire. Not sure if this worked. But replacing them with something that's OEM and new.

If you have solid wire in place of the fusible links, you might have blown injectors. The fusible links are there to protect injectors from power surges from the alternator or from trying to jump start the truck.

Yeah, it's somewhat a solid wire. Kinda wack the way he had it. Here's a pic.







I might as well pick up some injectors when I head out to the junkyard as well.
